I do research about what tools that he can carry out and he use it to do their works, which included his laptop, laptop charger, chisel set, some metals, and others tool( hammers and etc.)

Then,

I try to design a portable casing which can keep a chair and table in it so that when he was outside he still can have a place to do his works instead of do it on ground.

My overall size of toolkit is about 500mm(L)*350mm(W)*340mm(H)

I designed a small cabinet to keep all his chisel set in it using assembling mechanism. Other than keep his tools, it can be a small chair too. Other than that, there are table and chair(small cabinet)  that can expand out which he can put his table on the top of the toolkit and chair(small cabinet) with X shape legs to make it more stable when he sit on it(Step 3). When he don't need chair he can slide the table to his left hand side and sit on the ground and do his works too (Step 4).

I learned how to use different mechanism to minimize spaces and the measurement of ergonomics of a people, how to design something that make comfortable.
